OILING DEVICE. V

Application filed July 20, 1925. Serial No. 44,717, c

To (ill: whom it may concern: Be it known that], ALLAN O. CARPENTER, a citizen of the United States, and a resident of Corning, in the county of Steuben and State of New York, have invented a certain ()iling -1)evice, of which'the following is a specification accompanied by drawings.

This invention relates to oiling devices for compressors, pumps, and the like, but

more particularly to-an oiling device for duplex machines by'means of which oil or other lubricant is elficiently supplied to each crank for splash lubrication.

The objects of the invention are to produce a simple and efficient oiling device operated by an oil elevator of any suitable character which could be any form of pump and will supply the lubricant separately to the splash troughs from which the oil will be returned through an overflow chamber into the oil reservoir and elevator chamber at a lower level so that the oil may be used over again. 7

Further objects of the invention are to enable the compressor to stand atan anglelatorally and yet maintain suflicient oiling, and produce an oiling system operative for either direction of crank shaft rotation. Another objectof the invention is to enable the entire; oiling device to be inclosed within the crank case.

The invention is shown in one of its pre-- ferred forms in'the accompanying drawings, in which Figure 1 is a diagrammatic sectional elevation of a duplex compressorv having the oiling device applied thereto,

Figure 2 is a detail Vertical sectional view taken through the sump chamber containing the oil elevating gears, I

Figure 3 is a horizontal,sectional plan view taken through'the oiling device on the line 3-3 of Figure 1 looking in thedirec-tion of the arrows, and or Figure 4 is a view through Figure'E-B on the line 4-4-looking in the direction of the arrows.

Referring to the drawings, the cylinders A and B of the compressor are provided with the usual reciprocating pistons C and D driven from the crank shaft E having the cranks F and G which are provided with the usual splashers H and J. The compressor is provided with'the usual valves and intake and discharge connections and may be in the appended claims.

driven from any source of power, but these 7 splash troughs P and Q in the usual manner.

The-lower compartment L is also subdivided into a sump chamber S in which two gears acting as an oil elevator are located, comprising the gears T and U conveniently driven from the crank shaft E. The other .chambersof the lower compartment L comprise the oil receiving pockets V and V and the return flow chamber X, which return flow chamber communicates with the overflow chamber R by means of the passage Yand also communicates with the chamber S through the'passage Z;

The conduits or pipes a and I) connect the oil receiving pockets V and W with the splash troughs P and Q, respectively at a level above the bottom of said chambers, so that oil elevated into the oil pockets flows to the splash troughs, and may overflow from them over the partitions c and (1 into the overflow, chamber Rand from thence through'the passageY into the return flow chamber- X at a lower level and back into the chamber s. These partitions '0 and d' equivalent constructions without departing from the spirit of the invention as define I claim: I 6 1. An oiling device for duplex compressors, pumps and the like comprising in combinatiop, a crank shaft, and cranks, a

crank case, splash troughs, and an overflow chamber, a sump chamber at a lower level containing oil elevating gears, 011 receiving pockets, conduits leading from the oil receivmgpockets through the walls of and into the splash troughs respectively, and a return flow chamber at a lower level than the overflow chamber and communicating therewith and with the sump chamber.

2. An oiling device for duplex compressors, pumps and the like, comprising in combination a crank shaft and cranks, a crank case divided at its lower compartment into t'wo compartments having different levels, the higher compartment being again divided into an overflow chamber and troughs into which the splash oilers of the cranks dip, the lower compartment being also subdivided into a sump chamber containing oil elevating gears, oil receiving pockets, and a return flow chamber communicating with the said overflow chamber of the higher compartment, and pipes leading from the said oil receiving pockets through the walls of the said splash troughs for delivering oil to the said splash troughs.

In testimony whereof I have signed this specification.

ALLAN O. CARPENTER.
